What Happens If You Are Late for Your Corporate Taxes in Singapore (and How WLP Can Help)
Missing your corporate tax filing or payment deadlines in Singapore can lead to escalating penalties and enforcement actions from the Inland Revenue Authority of Singapore (IRAS). Understanding what could happen — and how experienced accountants can assist — is crucial for businesses of all sizes.
Estimated Notice of Assessment (NOA)
When a company fails to submit its Form C or C-S on time, IRAS may issue an Estimated Notice of Assessment (NOA). This is an automatic assessment based on available information, often without your actual return.
Key Steps to Take:
- Pay the assessed tax within one month of the NOA date — even if you intend to object. Otherwise, late payment penalties apply.
- File the overdue tax return immediately, attaching any objection letter if relevant, to allow IRAS to revise the estimate.
Failing to respond promptly can move you into deeper compliance issues.
Outstanding Return Notices and Composition Fees
If no NOA was issued or you didn’t act on it, IRAS may send a Notice for Outstanding Tax Return and/or Documents along with a composition fee.
What to do:
- Submit the overdue return and any required supporting documents.
- Pay the composition fee by the deadline. You may be able to appeal for a waiver or reduction if there are valid reasons.
This stage is your second chance to rectify the situation before higher enforcement steps kick in.
Notice Under Section 65B(3) of the Income Tax Act
If you still don’t file after the previous notice, IRAS may escalate to a formal statutory notice (Section 65B(3)). This gives you 35 days to comply — or risk being summoned to court.
At this point, previously unpaid composition fees still need to be settled.
Court Summons and Legal Action
Delaying beyond Section 65B(3) can lead to a court summons for the company and, potentially, its directors.
Possible outcomes at this stage include:
- Court fines (often up to several thousand SGD).
- An order to file overdue returns and pay all outstanding taxes and fees by a specified deadline.
- For particularly serious cases or repeated defaults, additional penalties may be imposed — including penalties as high as twice the tax undercharged.
Directors can also be held personally liable in certain circumstances, with higher penalties or even warrants in severe cases.
Late Tax Payment Penalties
Aside from late filing, failing to pay taxes by the due date triggers financial penalties under IRAS rules. Generally:
- 5% immediate late payment penalty on the outstanding amount.
- Additional 1% per month if the tax remains unpaid 60 days after the initial penalty, up to a maximum of 12%.
- IRAS may also appoint agents (like your bank or tenants) to help recover overdue taxes.
These penalties can compound rapidly, so timely payment is just as important as timely filing.
Why Timely Compliance Matters
Missing deadlines doesn’t just result in fines and legal risk — it can also harm your company’s compliance record with IRAS. A poor compliance history may make future extensions or tax negotiations more difficult.
